Changed the context type to key from raw for ERP5 kernel directory; added more params for kernel json file; md5 sum changed

Merge branch 'master' of https://lab.nexedi.cn/nexedi/slapos

* 'master' of https://lab.nexedi.cn/nexedi/slapos:
  openssl: Allow it to be build with make -jN   N > 1
  openssl: Convert patches to -p1

component/openssl: Fix build for make -j

Fix parallel build for openssl - out of the box it in parallel mode openssl build ~ 2 times faster, and with tuned cache and other setting ~ 3 times faster.

Please apply and thanks beforehand,
Kirill

For builds to be reproducible, we pin versions for used eggs and
buildout extensions, but 30d43f03 (use slapos.extension.strip to strip
binaries at the end of buildout process.) forgot to do this.

There is a story for OpenSSL build to be broken for `make -j`. Gentoo-
and various other people proposed fixes, at least from 2008, but for
some reasons (patch does not work with BSD make, upstream forgot to
apply, etc) they are not applied to main codebase.

What we can do is to "cherry-pick" the patch from Gentoo to speed-up
OpenSSL build. On a typical 8-cores i7 node, with the following test
buildout:

    [buildout]
    extends =
      slapos/stack/slapos.cfg
      slapos/component/openssl/buildout.cfg

after full build

                    time (rm -rf parts/openssl && ./bin/buildout install openssl)

    MAKEFLAGS=-j1   1m48s
    MAKEFLAGS=-j8   0m53s

and the timing does not subtract time to e.g. download the package from
network, so the building speedup itself is even more.

We'll soon need to apply/ship external patches for openssl with us, and
external patches and patches in general usually go in -p1 format.

Since patch-options is "global" - i.e. it affects all patches for
slapos.recipe.cmmi, this change is needed for us to keep
downloaded-from-somewhere patches as unmodified as possible.

In 2d7e6179 (wendelin.core: Add part/recipe how to build it from git
repository) I've added wendelin.core-dev part, but forgot to set :egg
variable inside it.

Hello web

Hello up there.

While studying how SlapOS works, I've turned helloworld example into real web-service.

New helloworld software-release was tested ok:

    - inside webrunner, and
    - instantiating in "raw" slapos locally under slapproxy.

Please apply and thanks beforehand,

Quoting @jerome:

    @kirr, we usually extends component/git/buildout.cfg and use
    ${git:location}/bin/git instead of git, in case git is not always in the
    path, especially in webrunner.

also use our own libraries more.
clean up rpy2 component.

because nodejs does not compile in testnode in webrunner
